Description

The expanded ceramsite and preparation method being prepared using spent bleaching clay
Technical field
The present invention relates to environmentally friendly waste utilization technical fields, and in particular to a kind of preparation method of expanded ceramsite.
Background technique
Currently, generalling use atlapulgite or granular carclazyte in petroleum chemical enterprise's oil plant carries out essence to lubricating oil, paraffin System.The regeneration and recycling of spent bleaching clay are a problem to be solved always, and up to 30000t spent bleaching clay is because being unable to get every year It is effectively treated and has to discard.During clay finishing lubricating oil, a large amount of oil-containing spent bleaching clay can be generated, these Spent bleaching clay oil-containing about 30%, wherein have about three/second is that good lubricating oil.There to be unit in carclazyte by modes such as extractions Point recycling, then spent bleaching clay becomes waste and is not available.
With the development of the society, the environmental consciousness of people is more and more stronger, for spent bleaching clay harmless treatment more and more by To attention.In the prior art for the processing method of spent bleaching clay also there are many, such as mechanical presses method, alkali wash etc., but these Method does not all handle spent bleaching clay fundamentally, and thus also will cause secondary pollution.
Summary of the invention
In order to solve above-mentioned the technical problems existing in the prior art, it is prepared into the invention proposes a kind of using spent bleaching clay The expanded ceramsite and preparation method arrived, this method have not only fundamentally handled spent bleaching clay, and being also prepared has compared with Gao Jing The haydite for value of helping.
One of task of the invention is to provide a kind of method for preparing expanded ceramsite using spent bleaching clay.
A kind of method that spent bleaching clay prepares expanded ceramsite, successively the following steps are included:
A is by spent bleaching clay, cosolvent, foaming agent and the uniform mix of water；
Gained mix is sufficiently stirred b, and is granulated to the ingredient after stirring；
Ingredient after step b is granulated by c is dried and preheats；
Ingredient after d preheats step c is roasted when temperature is 1000-1200 DEG C；
The haydite that e is obtained after roasting step d is cooling, sorts out and packages finished product.
The direct bring advantageous effects of above scheme are as follows:
As long as in general bulge theory thinks the silica of raw material in 48--70%, aluminium oxide is helped in 8--25% Solvent can be burnt within the scope of 4.5--31% to rise, and silica accounts for 62% or so in the component of spent bleaching clay after the recovery, oxygen Change aluminium and account for 18% or so, meets the condition for completing expanded ceramsite.
Above scheme realizes the recycling treatment to spent bleaching clay, and by following embodiments it is found that its obtained expansion The apparent density of haydite leaching is 2.4~2.8kg/m3。
As a preferred solution of the present invention, spent bleaching clay is butt and oil content is below 1%.
As another preferred embodiment of the invention, the cosolvent is NaOH or MgO.
Preferably, the foaming agent is hydrogen peroxide.
Preferably, in step c, drying temperature is 100~120 DEG C, dry 3~5h.
Preferably, it in step c, is preheated in Muffle furnace, preheating temperature control is 350~450 DEG C, and preheating time is 10~30min.
Preferably, calcining time is 5~20min in step d, the haydite in step e it is cooling in rotary cooling cylinder into Row.
Further, the w/v of the spent bleaching clay and foaming agent is 300/ (2~6) g/mL.
Another task of the invention is to provide the expanded ceramsite that the above method is prepared.
The expanded ceramsite being prepared according to the above method, the apparent density of the haydite are 2.4~2.8kg/m3。
Silica accounts for 62% or so in the component of spent bleaching clay after the recovery, and aluminium oxide accounts for 18% or so, and it is swollen to meet completion The condition of expanded haydite, the method for the present invention be spent bleaching clay have found practicable utilization approaches, and be also obtained have compared with The haydite of high economic value.
